Unquestionably fundamental! Start there and dominos fall very quickly.

“Our Homes Weigh a Tonne (of carbon per square metre)

Before a single appliance is switched on, an average all-electric Australian home has already emitted more than seven times the carbon it will produce over its operational lifetime.”

As I’m fond of saying, we can always change operating emissions once it opens, we can never change upfront carbon once it’s built.

Looking forward to “Let Me Sum Up” meme edition from now on

And now we’ve released our practical guide for circular procurement here! #SustMemeCE #circulareconomy gbca-web.s3.amazonaws.com/media/docume...

Front cover of budget paper number 1.

This week the Let Me Sum Up podcast sums up the climate and energy measures in the 2025-26 Federal Budget – admittedly slim pickings, leaving ample opportunity for @frankiemuskovic.bsky.social, @tennantreed.bsky.social and I to play armchair Treasurer!

Puff piece on @abc-news.bsky.social #abc730 program tonight about possible future gas shortage in Victoria was an overt attempt to peddle the gas industry’s ’drill, baby drill’ agenda.
We don’t have a gas shortage…just a shortage of political constraints on unfettered gas exports

Very fine list!

I admit to mostly using chatGPT instead of Claude, and I use it as a very simple assistant - fix formatting, do tables, check grammar. It has sped up some workflows. Also surprisingly helpful to help me do simple coding (not a coder, but I dable)

Doing some stuff in Australia if you are keen :)

What a great graph.

Somehow I don’t think that is an actual exclusive…

Addressing end of life emissions from a building at end of life today is not module C. It is different to addressing end of life emissions of a new building in 60 years (that is module C). Addressing the building at end of life today also is upfront carbon.

Well placed burp can be funny… so says a few five year olds :)

Which builds on our discussion paper where we realised that we needed to get people to stop thinking recycling when thinking circular. The two ain’t the same, and while there’s no such think as true circularity, we can try and get close :)

I now realise I have shared too many resources :)

Didn’t even get to the circular economy ones, like the below:

Thank you! We were very proud of it and now are doing a version to drive circular procurement :)

Our nature roadmap is on its way, and here is our consultation paper outlining what we think the built environment needs to reckon with.

gbca-web.s3.amazonaws.com/media/docume...

Five years later we did a review of the topic again, this time in a world that really thought of nature as critical, with TNFD and the Kunming-Montreal Buodoversity Protocol shaping up. This report made us decide to develop a Nature Roadmap.

Another batch, this time on nature. Two resources, with the first a review on what we needed to do to make the built environment more nature-friendly and biodiverse as we thought nature would become an issue of investable concern.

And more recently we expanded on social issues by releasing an incredible guide on what it means to create and measure social value

A few more resources that we’ve put out.

When we redeveloped Green Star, we wanted to move away from a narrow view of resilience to one that encompassed community and social resilience, so we put out a nice primer on why we did what we did :)

Very excited to be consulting on Green Star Futouts, the first rating tool in our system to put a circular economy as our key driver. Look forward to hearing what people think.

Direct/indirect is why. 37% of total global emissions are buildings (UNEP): 11% from upfront carbon, 26% from energy emissions. Of the 26%, 30% (6% as in graph) are direct emissions (gas, diesel, etc.), with rest indirect grid emissions attributed to buildings, included in the “power” sector.

Turns out all this electrification brings in some challenges, so we released a paper on grid-interactive buildings!

And an electrification guide for precincts.

gbca-web.s3.amazonaws.com/media/docume...

And for existing buildings too!! Cause those are harder to electrify, we needed a specific guide for them.

2) Our practical guides to electrification for new buildings, tells you all you need to know to build a future-proofed all-electric asset
